- Any code causing a linker mismatch needs to explicitly clear loading flags for their object to avoid asserting. This is to make the intention clear that rename will make loading correctly impossible when moving the object to a different linker unintentionally. So either clear the loading flags of the object (i.e. finish loading via load calls such as ConditionalPostLoad) or forcibly allow mismatching via the new flag.
- When marking an export as invalid in FLinkerLoad::InvalidateExport() we now also clear loading flags since it is wasteful to load invalid objects.
- Exports marked as invalid are no longer reset to be valid when the linker is reset for the object instance. This is to prevent reloading invalid objects when re-using a linker already resident in memory if a subsequent package load is requested.
- When UStruct upgrades UFields to FFields, the UStruct objects are marked as invalid to prevent reloading the objects unnecessarily
- Fixes an issue where since Rename can clear the linker for mismatched types, any calls to FLinkerLoad::InvalidateExport needs to be moved before the rename operation to be effective.
- CollectUnreachableObjects will no longer mark unreachable objects as invalid in the linkerloader. That code would mark objects as invalid until the linker is destroyed which incorrectly assumed would happen soon. If however a load for the same package occurs before the linker is destroyed, the in-memory linker would be re-used keeping the marked exports as invalid so those exports would not be loaded (even though they should have been).

[RN] UObject::Rename will always remove the renamed object's linker if the rename moves the object into a different package. As a result, any renames occuring while an object is loading will now assert instead of leading to hard to diagnose crashes long after the Rename call has completed. If renaming to a different package is intentional and the linker should not be cleared, the new flag REN_AllowPackageLinkerMismatch can be used to prevent clearing linkers on the object even though the linker is for a different package than the package has been renamed to be part of.

Add a different "key" structures to prevent mistakes with indexes.
Unregister the delay bindings when the source is released.
Store the FieldId, in the source itself. That reduces the amount of work when loading the view.
Add option to delay the events initialization (like we do for bindings).
The binding to evaluate "long path" view models are now separated from regular bindings.

MVVM: Big rework of the MVVM view compiler. It add supports for conversion function to go from complex to simple. Supports pin split on simple conversion function. Add ability to to support setter function with more than one argument. Build the list of all the sources.

IsEmpty is renamed to IsValid. It used to be that we wanted to know if there was a source and a path but now the IsEmpty is confusing.
Fix Widget rename for conversion function pins and event pins.
